Title: A sample-holder for a micro-hardness-testing machine
IPC: G01N3/40
Filed: 1968-04-04
Abstract: 1,214,865. Micro-hardness testing machine. EUROPEAN ATOMIC ENERGY COMMUNITY. April 4, 1968 [April 7, 1967], No. 16172/68. Heading G1S. The sample 1 to be tested at various points in a circle 4 on its surface, see Fig. 1, (not shown) is heated by wires 2, 3 and may be moved in a circle without itself rotating by means of two carriages 5, 17 sliding respectively on guides 6, 16. An electric motor 18 rotates gears 28 and a shaft 20 in a stepwise manner so that a pin 21 eccentrically mounted with respect to the shaft 20 and rotatable in a block 22 can give the compound movement to the carriages 5, 17 necessary to move the sample 1 in a circle beneath an indentor. The block 22 is integral with a slide 12 movable in holes 13, 14 in lugs 15, forming part of the carriage 5, so that when the shaft 20 rotates the eccentric pin 21 the block 22 reacts against the slider 12 which is held with its end 10 against the fixed stop 8, thus moving the carriages 5, 17 to give a circular path to the sample. The end 10 is held against the stop 8 by pull on a cord 7, this pull being insufficient however to resist the movement of the block 22 by motor 18. The cords 7 attached to an electric motor (not shown) are also used to pull the carriages between the buffer station 8, 9 which define respectively the place where indentations are made and the place where they are measured. A detector 19 monitors the angular position of shaft 20 and delivers this information to a control unit via electric wires which unroll along the guideway 6. When the operator is informed via the detector that the shaft 20 has rotated to a desired position he can stop the shaft by operating a disc brake 30.

Title: Improvements in sound producing devices
IPC: G01S1/72
Filed: 1923-06-21
Abstract: 217,056. Jackson, W. J. Mellersh-, (Submarine Signal Corporation). June 21, 1923. Diaphragm and plate vibrators.-In a soundproducer, particularly for subaqueous signalling, the sound-emitting member consists of a rigid mass of steel A which is mounted so as to vibrate as a whole without deformation by means of a relatively-thin elastic annulus a<1>, and is set into vibration by means of an electrodynamicallyoscillated copper cylinder L to which it is connected through coaxial elastic tubes G, G<1>. The cylinder L is located in the narrow air-gap between the mass A, which is magnetized by a direct-current winding B, and a surrounding magnetic collar M. The passage of alternating- current through other windings E, F sets the cylinder L into longitudinal oscillation, its movement being communicated, with a reduction in amplitude, through the elastic tubes G<1>, G to the mass A which vibrates in a piston-like manner to transmit sound waves to the surrounding medium.

Title: Improvements in devices for stretching and shaping spectacle frames
IPC: B29D12/02
Filed: 1950-06-28
Abstract: 683,921. Moulding spectacle-frames. AMERICAN OPTICAL CO. June 28, 1950 [June 30, 1949], No. 16175/50. Class 87 (ii). A device for use in stretching or reshaping spectacle rims when softened by heat comprises a substantially conical structure having a flexible continuous sleeve and a plurality of spaced longitudinally extending rigidifying elements inwardly of said sleeve to cause said sleeve to be longitudinally rigid but radially deformable, whereby it may be shaped to the shape desired of the spectacle rims by means of a pattern assembled therewith and held to said shape by said pattern. The rigidifying elements comprise rods 38 having their upper ends closely joined in circular fashion, e.g. by threading wire through holes in those ends, and having their lower ends bent to pass through holes in the flexible sleeve 43 and clinched as at 44 to prevent withdrawal. Recommended materials for the sleeve are beryllium copper or stainless steel. The pattern 28 or 29 (already in the machine which' gives the lenses the required contour) is placed on a block 22 which is adapted to seat either type of existing pattern. The block 22 screws onto a member 18 secured to the upright 12, alignment being achieved by a post 17 entering a recess 19. An annular member 36, having a contour substantially that of an average lens, is situated near the bottom of the upright, which also bouses an electrical heating element 14. The reinforced sleeve is forced downwards till the rods 38 engage the pattern 28 and cause the sleeve to assume the contour of the pattern, and the heat is turned on. One of the rims of the spectacle frame is then fitted over the sleeve and the heat softens the material of the rim to enable it to be forced downwards and expand to assume the shape of the sleeve, i.e. of the pattern 28 or 29. The sleeve, reinforcement, instead of consisting of rods, may be a corrugated metal sheet 59 and may be given a conical shape by closing the top corrugations and expanding the bottom, and then hardening the unit. The member 36 may be detachable and of various shapes conforming to the shapes of the patterns 28, 29. Other parts of the spectacle frame are shaped with the aid of an anvil 48 which, after removal of the sleeve and its reinforcement, may be secured to the block 22 so that heat is transmitted to it. The anvil is substantially conical with a tongue 50 at its top and a slot 49 at its bottom. The bridge of a spectacle frame is stretched and shaped by working it by hand on the conical anvil. A nose pad can be shaped by working it against the tongue 50. A temple can be shaped by working it in the groove 49.

Title: Improvements in electric switching apparatus
IPC: H01H67/26
Filed: 1923-06-22
Abstract: 221,881. Relay Automatic Telephone Co., Ltd., and Ward, F. M. June 22, 1923. Automatic exchange systems; selectors.-In a switch with sets of normally-adjacent contacts C arranged in rows and columns, the contacts in each row are controlled by a relay R, and a particular set is operated upon energization thereof by means of a rotary shaft B which selects a column by bringing resilient arms W below the contact sets. The contacts comprise springs c and strips c<1>, the latter extending the width of the switch, and are operated by the armature A of the relay R through the engagement of the arm W resting on ridges a<1> in operative position with a member L. The shaft B is rotated by means of solenoids S, S' and its movement is limited by pins p which are projected into the path of a member M by solenoids T corresponding to the columns. A connection is maintained by the selected relay R only. and the shaft is restored to its central position by a spring 0 acting on a cam RC. As applied to a non-numerical switch, Fig. 6, when one of the lines IL becomes a calling line, a solenoid T operates according to the first idle outgoing line OL. The shaft B then rotates to the selected column, and the relay R associated with the calling line energizes and locks, so that the shaft is free to effect further connections. As applied to a numerical switch, Fig. 7, the incoming line IL is multipled through all the rows, and each column represents a numerical group. The solenoid T corresponding to the required numerical group is energized, and the shaft B rotates to the selected group. A relay TRO in circuit with the solenoid T connects the test circuits of all the lines in the group to the corresponding relays R, each of which upon energizing opens the circuit of those above it. To ensure that no relay R shall operate until the rotation of the shaft B is completed, contacts ON are provided which are controlled by a relay operated over springs closed by the pressure of the member M against a pin p. The relay R associated with the first idle outgoing line OL energizes and locks, the remaining parts being restored to normal. The opening of the test circuit of the selected line OL serves to mark it busy. In a modification, only one resilient arm C is provided, and is raised initially to select a row of contacts. Specification 29615/19 is referred to.

Abstract: 436,023. Photo - electric cells. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and SIMMS, C. H., c/o General Electric Co., Wembley, Middlesex. May 31, 1934, No. 16311. [Class 39 (i)] In the manufacture of photo-electric cells of the type wherein caesium vapour acts upon a cathode of oxidized metal such as silver, the variability of the emission is reduced by exposing the interior of the vitreous envelope to attack by caesium or a caesium compound before the final formation of the sensitive cathode is begun. According to one method, a caesium cell is prepared in the usual way and sealed off. It is then baked for several minutes, at 400‹ C. for borosilicate glass, reopened and washed out with water, and with nitric acid also if the silver is a layer on the wall. The cell is then remade, the process being repeated if necessary. In a preferred method, the envelope containing the anode but not the cathode is sealed off with a little caesium and baked until the glass is sufficiently attacked. The cathode is then introduced and sensitized in the usual manner. The Provisional Specification comprises the use of other alkali metals in place of caesium.

Patent GB-1247782-A (GB)
Title: Device for tabulating printed numeric characters from the right
IPC: B41J21/04
Filed: 1969-03-28
Abstract: 1,247,782. Selective printing. ING. C. OLIVETTI & C. S.p.A. 28 March, 1969 [26 April, 1968], No. 16498/69. Heading B6F. [Also in Division H4P] In type-printing telegraphic apparatus, the transmitter is provided with the conventional alphanumeric keyboard and a numerical keyboard. Only one keyboard is operable at a time, the other being locked by an electromagnetically operated universal locking bar (131, Fig. 2). The numerical keyboard is associated with a mechanism for tabulating from the right which comprises means for entering numeric character code combinations into an accumulator, of the kind described in Specification 1,178,569 (see Division H4), a control member which commands the transmission of the stored code combinations from the accumulator to a teleprinter (Fig. 1), and means for automatically transmitting a "back space" code combination to the teleprinter, but not to the accumulator, each time a numeric character code combination is entered into the accumulator when a numeral key of the numeral keyboard is depressed. When the complete number has been composed, release key (214, Fig. 2) is depressed thus commanding the reading and therefore the transmission of the code combinations contained in the accumulator. These code combinations are transformed from parallel to serial form, as described in Specification 1,178,569, and transmitted to the teleprinter which prints in normal fashion arriving at the right hand margin from whence it started. The mechanism for generating a "back space" code combination automatically, without entering it in the accumulator, comprises a bail 147 fast with a fixed shaft 149, Fig. 7, and provided with a profile 151 having a succession of teeth 152 and gaps 153 corresponding to the "back space" code combination. The teeth and gaps are sensed by the projections 154 of a series of sensing elements 156 pivoted on a bar 157 carried by a frame 158. In operation, a rocking lever 179 shifts the frame 158 upwardly together with the sensing elements 156. If a projection 154 encounters a tooth 152, the sensing element 156 acts by means of a projection 173 on an arm (174, Fig. 8), bringing a lever (63), into one of two positions. If, on the other hand a gap 153 is encountered, the lever (63) moves to the other of two positions. The transmission bars (58) are thus positioned selectively together with sliders (62, Fig. 5). The wedges carried by the sliders (62) are sensed as described in Specification 1,159,835 (see Division H4) to provide the "back space" code combination in serial form, which is then transmitted to the teleprinter.
